I watched this video of Pye on YouTube: While I was impressed with his idea of using CTO gels to produce golden hour images, I was taken aback when he said he used ISO of 1600 on his Canon 5D mark iii. I have come across this message that 5D mark iii behaves extremely well in low light conditions. But doesn't ISO 1600 sound too high? And I don't find any problem in the pictures that he showed in his video. I assume he used post processing to drop noise. 1) How do you control noise in post production - Do you use any plug-in or just camera raw? 2) How do you maintain sharpness while reducing noise? 3) Can you post some pics. that you shot at high ISO with acceptable noise level and sharpness pl.?
